It felt kind of like a Kennedy -meets-Weird-Al Yankovich-day at the opening concert of the 2015 Wells Fargo Chamber Music series at Spoleto.  Series director Geoff Nutall, who is also first violinist of the superb St. Lawrence Quartet, is just as fashion-forward as his single-named British contemporary and was in mid-Festival sartorial form. This year’s composer-in-residence Mark Applebaum, whose startling and oddly mesmerizing piece Aphasia anchored today’s program, may be the only man–white or black–in America (other then Weird Al) to still sport an Afro. Almost certainly, he is the only composer to write a piece to be performed by a florist.

Aphasia is  a scary word for people my age, meaning the loss of ability to understand or express speech, caused by brain damage, like that caused by strokes.  Applebaum’s Aphasia is a 9-minute piece expressly written for a “singer” to perform without making a single sound. Premiered in February 2011, it consists of hundreds of transformed vocal samples derived from the voice of professional baritone Nicholas Isherwood and set to a score of nonsense hand signals coordinated to each sound.

Based on everyday activities, the hand gestures were recorded as a written musical score, using icons with names such as “give me the money” and “Post-it Notes.”  Applebaum says these gestures are intended to reflect his own fascination with “absurdity that seems to be the consequence of tedious, obsessive attention to ridiculous things.” Or, in other words, how bizarre the actions of the mundane routine of activity seem when they are examined out of context. Applebaum performed the piece himself.

While the piece was inspired by a conversation between Isherwood and Applebaum, the idea to write a piece for a mute singer with hand motions was Applebaum’s own “obsession.” He says his intention was to have Aphasia come across as a metaphor for “expressive paralysis,” something that unnerves him every time he “confronts the terror of composing a new piece.

Applebaum, who teaches at Stanford, is sometimes called “the mad scientist of music” for his extensive use of technology, and “invented and found” instruments–but his pieces are also curiously rooted in human emotions like joy, boredom, fear, despair, generously laced with Woody Allen-level angst.  A zest of narcissism here, a dash of paranoia there, a couple of sprigs of self-loathing on the side.  The result is work that is highly personal and curiously “music-ish.”  As Applebaum likes to say the interesting question is not “is it music” but “is it interesting?”  That, it certainly is.

There’s more Applebaum to come at Spoleto in the next week-and-a-half. The Bank of America Chamber Music series consists of 11 separate programs that run about 1 hour and 15 minutes, presented three times each.
